QUESTION 245
Which two statements best describe the signalling requirements of virtual circuit setup of VPLS and exchange of reachability information (MAC addresses)?
A. Cisco VPLS does not require the exchange of reachability (MAC addresses) information via a signaling protocol. This information is learned from the data
plane using standard address learning, aging, and filtering mechanisms defined for Ethernet bridging.
B. Cisco VPLS uses directed LDP as a signalling protocol to exchange reachability (MAC addresses) information to avoid maintanance of ARP cache.
C. In Cisco VPLS the virtual circuit setup uses Multi-Protocol BGP as autodiscovery and signaling mechanism. Using BGP allows BPDUs to be propagated
across VPLS in a scaleable fashion.
D. In Cisco VPLS the virtual circuit setup uses the same LDP signaling mechanism defined for point-to-point services. Using a directed LDP session, each
provider edge advertises a virtual circuit label mapping that is used as part of the label stack imposed on the Ethernet frames by the ingress provider edge
during packet forwarding.
